Abstract

The Particle Listings 2000 edition gave the recommended value of antiproton mass, for the first time, to be within 5 × 10−7 in the relative deviation from the proton mass; this can be a test of the CPT invariance. The value was derived by our precision 3-body calculation to analyze the laser spectroscopy data of metastable states in antiprotonic helium atoms taken at CERN. The 2002 edition reported an one-order smaller value, 6 × 10−8, based on further development of both the experiment and our calculation.
